Zero benefit? VFR is VFR, see and be seen in Class G (cheers Dick!) You are forgetting IMC conditions, when the only other aircraft you are mixing it with are other IFR a/c in IMC. Would you like directed traffic information based simply on pilot estimates, or do you think you might get a 'benefit' out of a DTI service from ATC who can actually 'see' both you and the conflicting aircraft and pass advice accordingly?
This thread should have been titled 'ADS/B Mandate - Axe to Grind', but we all know Dick's penchant for the ersatz dramatic attention seeking one liners..besides, no one else would have posted.
